Hmmm. That's not a documented function. I had a look at the source,
and I can't see how it works. It accepts a node as its only argument,
and it doesn't seem to perform any comparison as it executes. How then
would I get it to stick to just the one type of sibling, and how would
I get it to stop when it ran out of similar siblings?
Thanks as always for any pointers.

You'll want to leverage Prototype's nextElementSibling function.
That function grabs element.nextSibling and traverses until it finds
an an actual element (by checking nodeType).
You could wrap a function around that which stores the tagName of
the first element it matches, and then continues to find
nextElementSibling until it either returns null, or break when the
tagName doesn't match the original tagName.
Take a look at the innards of Element.adjacent and
Element.nextElementSibling for an idea of what I mean.
Best,

I have a structure like this inside a parent DIV:

And I'd like to be able to get the paragraphs between two heads, or
between the last head and the end of the parent DIV.
Element.adjacent('p') doesn't do what I need -- it returns all the p
tags in the entire DIV, since everything is at the same level. If I
get a reference to the first element following the head, how could I
get all similar elements up to but not including the next head? I'm
trying to find a purely structure based way to do this, rather than
adding classnames to the elements.
Thanks,
Walter
